An alternative to classic marketing – LED displays

Author: Vedran Kovačević

Surely you’ve recently noticed an increased number of advertising screens in urban areas, boasting constantly interchanging various animations, pictures, texts and videos. These are mainly external (outdoor) LED panels, which for many reasons replaced the classic billboards and advertisements. The first reason is flexibility, since it is very easy to manage material being broadcast on the screen, and you simply can start a new campaign, add new items on offer, change the prices advertised and the like. The great advantage of these displays is the fact that they are made with LED technology, which has proven to be of quite low power consumption due to the amount of light emitted. And of course, LED screens are definitely much more elegant and professional solution compared to “vintage” slabs, especially those that are damaged and faded under the influence of weather conditions.

SP Sistemi, as an IT company oriented to all kinds of requirements of business users, decided to add to our offer the configuration and implementation of both outdoor and indoor LED screen. Our expertise and competence was recognized very quickly by companies with the need to promote their product and we have received the first inquires, and at the end of October the first installation of LED panels was carried out.

LED screen is one of the P10 class, which is ranked somewhere in the middle on the scale of all kinds of outdoor LED screen in terms of quality and price. The ideal distance from the screen for the best and “cleanest” image is 20 meters, so the LED screen of these specifications makes it an excellent solution for advertising on the side of the road or on residential or commercial premises. One LED panel module is the size of 96 x 64 x 14 cm. It is possible to connect multiple panels in a “series”, and thus get a much bigger picture. In this case, there is a main panel in which the controller for screen management is, that needs to be connected to other panels.

The LED display is controlled by software called LedArt. The program is installed on the computer that will be connected to the panel. The program interface looks and works almost like the well-known MS PowerPoint. You create slides, and on each slide it is possible to insert a picture, animation, text and video, or the combination of all the above formats. The main controller panel also has an audio jack, so it is possible to connect the speakers to the LED screen and playback audio from video material.

There are several ways to connect to the LED panel:- mrežnim kabelom direktno iz računala;

– connecting the panels using a network cable to a network device (switch, router) and accessing it through a computer that’s on the same network as the LED panel;

– creating a USB stick that is inserted into the controller, and the panel copies the data from it to its memory (buffer)

In the event of LED screens turning off (power failure or unintentional human error), when it starts up again, it begins to reproduce the material which aired at the time of shutdown, because the controller stores the last presentation in its buffer. This fact is important if we consider the following scenario: creating a bootable USB stick, inserting it into the controller, turning the LED display on, playback from USB. If the stick is removed from the panel after the start of playback, the screen continues to broadcast the default material. Also, if the LED display is turned off, the  controller loads the last performance from memory, which means it is not necessary to re-create the USB stick and insert it into the controller of the panel, but it automatically from your memory plays this material. The same thing goes for networked configuration of the LED screen: if there is no need to change the material being broadcast, after re-ignition is not necessary to re-send the material from the computer to the screen.

It should be noted that the controller in the panel can read materials only with the USB stick is, which is in FAT32 format. If the LED display attempts to reproduce material from USB which is in NTFS format, the controller will behave as if the stick is empty.

In conclusion, we can state that LED displays are not only the present, but definitely the future of advertising in public places. Their numerous playback options and easy handling make them ideal solutions for companies that want to promote and advertise their work in a modern and efficient way.
